There's now a third William and Sly game! Coming Spring 2024:

Hey guys, I’ve started work on a possible William and Sly 3. Follow me on facebook for updates! https://www.facebook.com/LucasPaakh/


It feels good to be finally submitting this. I hope you all have fun! Merry Xmas. :3


The game should save automatically, but opening the map will do a manual write to the HD. This might cause a moment of lag on some computers. So, DON'T PANIC! lol

If you want to make sure your game saves, open the map before you quit. It should be fine even if you don't, but a tester had an issue so I threw a flush statement in as a failsafe. :3

I just added the William and Sly games on steam, so you can also play natively in fullscreen if you're interested!

one of my fave games for some reason, has been in my mind a lot recently. music is insane wish it was on spotify. gives me a very weird but welcome feeling. excited for 3rd game!

I used to play this game for hours as a kid on a random website and since flash had shut down I haven't been able to play it again until now. Thank you so much for letting me relive my childhood.
